List of identified hot spots

from Wikipedia, the free encyclopedia

The following table gives an alphabetical overview of 45 volcanic areas worldwide that have been classified as hot spots based on at least two of four typical characteristics . Positions 1–44 of the list follow the list by Bernhard Steinberger (see literature). For further items, see individual certificates. Other authors name different, sometimes significantly higher numbers of hotspot volcanoes.
